This is a super easy hat, knit entirely in the round with no increasing or decreasing.
Instructions are given to help you make the hat to fit you based on your measurements and gauge. A reference chart is included so you can make the hat for someone you can’t measure, either because they’re not nearby or you want to surprise them (stealth knitting!) I include the actual numbers I used to make my adult medium hat.
Yarn: American Worsted
Skills: basic knitting skills (casting on, knit and purl stitch, basic increases and decreases, binding off), knitting in the round
